I would definitely expect an exception to be raised, but it's not
happening. :-( Something seems to be going awry deeper in the call to
readKey. Attached is a new foo.py that eliminates the pyatpi
references. The same test procedure applies:
1) Run brltty in one terminal
2) Run foo.py in another
3) Kill brltty
4) foo.py seg faults
I'm not sure how to debug this.

brlapi_readKey will return -1 and the brlapi_errno variable will contain

Yes.
Not sure how this works in Python,
That should be translated into the corresponding OperationError being
raised.
